Websocket Php
This project is a PHP library designed for establishing persistent, bidirectional communication channels using the WebSocket protocol. It functions as both a client and a server implementation, providing the necessary tools to initiate connections with remote endpoints or host custom messaging services.
The library manages the full lifecycle of network connections, including the initial HTTP handshake negotiation required to upgrade standard web traffic to a persistent stream. It utilizes low-level stream resources to handle data flow and incorporates automated heartbeat signals to monitor connection health, detect timeouts, and ensure stable communication.
The implementation relies on synchronous blocking input and output operations, processing data through frame-based encapsulation to maintain protocol compliance. The library is available as a package for integration into PHP applications requiring real-time data exchange capabilities.
Features
- WebSocket Clients and Servers - Implements both client and server-side logic for establishing persistent bidirectional communication channels using the WebSocket protocol.
- Real-Time Communication - Enables persistent, bidirectional data streaming between applications and remote servers for instant updates.
- Connection Lifecycle Managers - Tracks active connections and uses keep-alive signals to manage session durations and perform clean resource cleanup.
- Data Framing - Encapsulates outgoing messages into binary packets with specific headers to ensure correct transmission over the underlying stream.
- WebSocket Servers - Facilitates the creation of custom server-side implementations for managing persistent, bidirectional communication channels.
- Connection Management - Monitors and maintains the stability of network connections throughout their lifecycle using automated heartbeats.
- Protocol Upgrade Negotiators - Transitions stateless HTTP requests into persistent bidirectional streams by performing the initial protocol upgrade handshake.
- Stream Socket Implementations - Provides reliable, ordered byte stream communication using low-level PHP stream resources.
- WebSocket Connection Establishment - Initiates and manages persistent bidirectional communication channels with remote servers.
- Liveness Heartbeat Monitoring - Monitors the active status of network connections via periodic heartbeat signals to detect timeouts and ensure stability.
- Real-Time Frameworks - Provides a toolkit for building interactive applications that require low-latency data streaming over standard web protocols.
